I installed an Update yesterday, and after the update i couldnt open certain apps, so i deleted Them and tired to install Them again. Then I found out that my google play store wasnt Worning either. It just shows a White screen, where nothing happens. I have tired clearing both cache and app date from both play store and other google play services. Please help me!

Try going to settings,apps,all then tap the three dots on the top right hand of screen, tap reset app preferences.If the update was Google play store then uninstall update from Google playstore

I fixed it! Finally! Here's what I did on my Samsung Galaxy S7 Edge:
Settings: Applications: Application Manager: Google Play SERVICES: clicked on the 3 little dots at top right: Uninstall updates...then it gave me an ANDROID DEVICE MANAGER WAS SET AS A DEVICE ADMINISTRATOR message: I unchecked the button to disable the android device manager as a device administrator: back to uninstall updates from 3 little dots at google play services and uninstalled updates. Closed settings: opened google play store...yay it worked! It reinstalled the play store and all is well.

Hello, I just wanted to thank you for this, i have been having issues with this for a while on and off, I posted on the google plays forum and got no answer, so this actually working was really useful!
